To all whom it may concern: i Be it known that I, HARRY W. sPANGLER,

a citizen of the United States, residing at Allentown, in the county of Lehigh, State ofPennsylvania, have invented a new and useful Bottle-Closure; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art 'to which it appertains to make and use the same;

' This invention relates to bottles, jars and like receptacles,and particularly to an improved closure therefor, and an object of the invention is to provide a closure consisting of two pivoted disks similarly constructed, each to partially rotate relative to the other, and each having a semi-circular flange curved in 'cross section, so that when one disk is rotated,its flange will be brought diametrically op osite= the flange of the other disk, therel y holding or locking the closure on the bead of the open end of the bottle.

- A further object of the invention is to provide means on one end of each flange, whereby the disks may be partially rotated for. removing and applying the cover or closure to the bottle. y

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set 1 I forth, shown in the drawings and claimed.

In the-drawings:-

Figure l is aview in perspective of the upperpart of the bottle, showing the cover or closure applied.

Fig. 2 is a perspective viewlof the upper end of the bottle, showing the cover or Fig. 3 is a sectional view on line of Fig. 1.

Fig. at is a plan view of the cover or closure, showing parts broken away and parts in section, to more clearly disclose the structure.

Referringmoreespecially to the drawings, 1 designates the neck of the usual form of milk bottle, 'the upper outer portion of the open end of which is provided with annular bead 2, and 3 designates the closure or cover for the bottle. This cover or closure consists of a pair of disks 4 and 5, which are pivoted together axially so as to Specification of Letters Patent.- Paijented Sagpt, 11, 191?, Application flied April 12, 1917. Serial No;

rotate partially relatively each other, by means of the rivet 6.' Each of the complemental disks may be partially rotated, and

both of said disks are provided with semi other. The flanges 7 and 8, are curved in.

cross section,so as to fit and engage the head 2, that is, when the two disks are disposed, as shown in Figs. 1 and 3, whereby the cover or closure may be held "on the open end. of the bottle, as shown. The disk 4, on its edge, adjacent the cut away portion 9, is provided with a slight flange 11, as

shown on Figs. 2 and 3, clearly. This flange is curved. in cross section, and is designed.

to engage, and overlie the edged portion of a fiber packing 12, as shown at 13, so as to hug the packing close to the upper edge of the open end of the bottle. The flange 8, when the two disks of the cover are arranged, as shown in Fig. 3, overlies the flange 11, and owing to the flange 8 engaging under the bead, the flange 11 is held tight against the edge portion of the pack age. The flange 7 of the disk i'also overlies the edge portion of, the" ,fiber packing, at various, points diamet-rioallyopposite the flanges 8 and 11, thereby additionally holds ing, the packing secure. Referring to the drawings, it will be seen that the flanges and 8 are provided'with laterally extending cars 14, one at one end of each of said flanges? and -8. In applying the cover or closure to a milk bottle, the two disks are so rotated partly as to position the semi-circusume positions diametricallyof-posite each other, and the flanges 7 and 8 correspond ingly diametrically opposite e ch other inf which case ,the cover or closure will be locked securely on the bead of the mouth end of the bottle. A reverse partial movement of disks will permit the removal of the cover.

The invention having been set forth, What is claimed as new and useful, is

1. A closure for a milk bottle, comprising a pair of complemental disks pivoted together-axially, said disks having semi-circular flanges curved in cross section to engage under the head of the mouth end of the bottle, and provided with semi-circular cutaway portions, the flange of each disk bein idiametrically opposite the cutaway portion of said disk, so that by partially rotating the disks, may assume positions 1n registration with each other, whereby the cover may be applied or removed on or from the bottle.

2. A closure for a milk bottle, comprising a pair of complemental disks pivoted together axially, said disks having semi-circular fian'ges curved in cross section to engage under the head of the mouth end of the ottle, and provided with semi-circular cut away portions, the flange of each disk being diametrically opposite the cutaway portion of said disk, othat by partially rotating the disks, may assume positions in registration with each other, whereby the cover may be applied or removed on or oil" the bottle, one end of each flange having a lateral ear, whereby its respective disk may be rotated,

said ears adapted to cooperate to limit the disks with the cut away portions in registration, the ear of one flange to cooperate with one end of the other fiange to limit the disks in their closed positions.

3. A closure for milk bottles, comprising a pair of complemental disks having semicircular flanges curved in cross section and provided with semi-circular cut away portions, the flange of each disk being diametrically opposite the cutaway portion of said disk, and means for pivotally uniting the disks axially, whereby the disks may be retated to register said cut away portion.

4. A closure for milk bottles, comprising a pair of coinplcmental disks having semicircular flanges curved in cross section and provided with semi-circular cut away portions, the flange of each disk being diametrically opposite the cutaway portion of said disk, and means for partially uniting the disks axially, whereby the disks may be rotated to register said cut away portions, and means carried by the flanges for limiting the disks in their closed and open positions. In testimony whereof I have signed. my name to this specification in the presence oftwdsubscribing witnesses.
